Corrected entry: In the American edition, page 188, Slughorn says, "One tiny bottle of felix felicis is enough for twelve hours' luck. From dusk til' dawn, you will be lucky in everything you attempt." But then on page 476, Harry says, "I don't reckon I'll need all of it, not twenty-four hours' worth."
